Birdproofing



Patented Jan. a, 1939 UNITED Isfrlirlzs PATENT OFFICE Claims.

This invention relates to Improvements in birdproong.

Its object is to provide an inexpensive material to be applied to buildings or other structures to 5 prevent birds from alighting thereon, which is simple in construction and may be readily applied. It is common practice to apply wire netting to structures which are subject to the bird nuisance, but this expedient is unsightly, somel0 what diiiicult to apply and has the unsurmountable disadvantage of catching leaves, papers and other dbris.

One of the purposes of my invention is to overcome these objectionable features and to provide a material which is neat in appearance and selfcleaning. y

These and other objects, of the invention will appear in the following specification in which I will describe several embodiments of the invention, the novel features of which will be pointed out in the claims.

Referring to the drawing, Fig. 1 is a perspective view of an embodiment of my invention in which the material is made up of an assembly of interlocking units;

Fig. 2 is a side elevation of the structure shown in Fig. 1;

Fig. 3 is a perspective view of a part of a simplied construction of material for the same purpose;

Fig. 4 is a side elevation of the structure shown in Fig. 3;

Fig. 5 is a perspective view oi a further modication; and Fig. 6 is a side elevation of the structure shown in Fig. 5.

In Figs. 1 and 2, a wire is bent into the form of a horizontally disposed loop III. Thence it is 4bent upwardly and downwardly to form the upstanding portions II and I2 which are preferably in contact with each other throughout their length. At the lower end of the portion I2, at approximately the level ofthe loop I0, the wir'e is bent at right angles to the portions II and I2 to form a side piece I3. At a xed distance from the portions II and I2 the wire is bent upwardly and downwardly vto form similar upstanding portions I4 and I5. At the lower end of the portion I5 and at the level of the side piece I3, the

wire is bent inwardly at right angles to the similar upstanding portions I1 and I3, thence equal length, as are also the upstanding por- 5.

The structure thus formed constitutes a unit designated generally by the letter A.

'I'he nextr unit, designated generally by the letter B, comprises loops IDB, 22B, side pieces I3B, l0 ISB, a transverse end ISB and upstanding portions I4B, I5B and I1B, IBB.

A third unit, similar to unit B and designated generally by the letter C, is shown in Figs. 1 and 2. It comprises like parts and its loops are desig- 15 nated by IUC and 22C.

These units are assembled by slipping the loops IIIB and 22B of unit B over the upstanding portions I4, I5 and I1, I8 of unit A and similarly slipping the loops IIIC and 22C of unit C over the 20 upstanding portions`I4B, I5B and I'IB, I8B of unit B. Any number of such units may be interconnected to form a structure of desired length.

The material thus formed may be attached permanently or removably to window sills, door 25 headers, domes or ledges of any desired structure. It is sumciently exible to conform to curved structures, such as arches. The mesh or distance between the upstanding portions is determined by the size of the birds to be guarded 30 against. Birds will not alight upon this material, nor can they obtain a foothold on it as they can on wire netting. The top of the material is entirely open so that it will not retain any foreign matter which falls into it. Where exposed to the elements, as it generally is, it will be wind sweptand remain'perfectly clean.

A simple construction is shown in Figs. 3 and 4. In this case a plurality of inverted wickets are welded at equally spaced intervals to longitudinal rods or wires 30. 3|. Each wicket has upstanding portions 32, 33 and a transverse base 34. As shown, the portions 32, 33 are of equal length and the distance between the wickets is the same as the length of the bases 34. The wickets are 45 shown as welded at right angles to the rods, but these relative dimensions and this particular arrangement may be varied without departing from the invention. This material is made in indenite lengths and may be cut into pieces of 50 the size required.

The construction illustrated in Figs. 5 and 6 comprises a plurality of spaced longitudinal rods or wires 40, 4I, 42, 43, 44, to which are welded at similarly. spaced intervals. a plurality of trans- 55 verse rods or wires I6, IB, 41, 48, I9, l0, Il, 52, 53, I, 55, 56, 51. As shown, comparatively long uprights 60, tl, $2, 63 are welded at spaced intervals to the outside longitudinal rod Il) with three shorter uprights 1D, 1|, 12 between each of them. Similarly, comparatively long uprights 64, B5, 66, 61 are welded to the' outside rod 44 with three shorter uprights 13, 1I, 15 between each of them. Three shorter uprights 16, 11, 18 are shown welded to the transverse rod 45 between the uprights 60 and 64 and similar short uprights are on the transverse rods 41, 53 and 51 between the longer uprights 6l, I5; 62, 66 and. 83, 61, respectively. Similar short uprights are welded to the other transverse rods, as shown. Of course, this arrangement of comparatively long and short uprights may be varied at will.

This arrangement has the advantage of keeping away birds of different sizes more effectively.

Other variations and constructions may be used Without departing from the spirit and scope of the invention and I intend no limitations other than those. imposed by the appended claims.

What I claim is:

1. Birdproofing material comprising a plurality of spaced parallel longitudinal bars, a plurality of spaced parallel transverse bars connected to the longitudinal bars. and a plurality of spaced uprights of dinerent lengths welded to the points of connection between the longitudinal and transverse bars. said uprights having free upper ends.

2. Brdproofing material comprising a pair ot spaced parallel longitudinal bars and a plurality of inverted rectangular wickets welded to said bars. v 3. 'Blrdproong material comprising a pair of spaced parallel longitudinal bars and a plurality o1' inverted rectangular wickets welded at their corners to said bars.

4. Birdprooilng material comprising an assembly of units, each unit being constructed of a continuous piece of wire with its ends bent into loopsand intermediate parts forming spaced parallel side pieces, upright portions and a transv #rse end, the loops of each unit being adapted to engage the upright portions of an adjacent unit.

5. Birdproong comprising an assembly of units, each unit being constructed of a continuous piece of wire bent toform spaced parallel side pieces, upright portions, a transverse end and loops at one end arranged to engage the opposite end of an adjacent unit.
